The EOS 7D Mark II is Canon’s flagship APS-C sensor DSLR, boasting a 20Mp resolution and a host of high-end features. It’s a popular choice for many serious enthusiasts and semi-pro photographers, so we’ve tested over 300 lenses on it to help you pick out the best one for you. In this first part of a two-part review, we round up the best zoom lenses for the Canon EOS 7D Mark II.

With a full-frame 18-Mpix CMOS sensor and twin Digic 5+ processers that’s capable of continuous bursts of up 12 fps – the fastest of any professional DSLR currently - the Canon EOS-1 Dx is the firm’s flagship press camera. We’ve assessed it with over 100 EF mount lenses, to see how well they perform. Read on to find out which models are the best optically and which, if any, you should avoid.

One of the four lenses announced at the time of the introduction of the Sony A7 and A7R, this high-grade G-series telephoto zoom looks like a promising addition to the range. Read on to find out how well it performs on the 36-Mpix Sony A7R.

Introduced in July this year, the EOS 70D at first sight seems like a regular update to the maker’s mid-range EOS 60D model. It shares a number of features with the firm’s existing SLR range including a 19-point cross-type phase detection AF system, a 3-inch (1.040M dot) articulated touchscreen and built-in WiFi connectivity with remote viewing and image transfer. The camera can also shoot at up to 7fps and has 1080/30p video recording with stereo sound using an optional external microphone.

After the runaway success of the full-frame 35mm f/1.4, Sigma is taking the initiative with this new ultra-high speed, pro-level standard zoom designed for APS-C format cameras. The specification is particularly promising, but does it mean the end of fixed focal lenses for APS-C? Read on to see how well this cutting-edge model performs in our labs.

In the lead up to Photokina 2012, Canon announced the new Canon EOS 6D full-frame entry-point model within days of Nikon publicizing their most-affordable full-frame camera to date, the 24-Mpix D600. While the EOS 6D boasted some attention grabbing features including built-in WiFi and GPS and slightly undercut the Nikon on price, it couldn’t match its rival in one or two key areas, namely the less populated AF system and lower resolution sensor.

Launched in February 2011, the Sigma 50-150mm f/2.8 EX DC APO OS HSM is a trans-standard zoom lens aimed at APS-C camera users. On these APS-C models, the crop factor of the sensor (1.5x on Nikon and 1.6x on Canon) makes it comparable to the 70-200mm focal length on a full frame camera, but arguably with an even more versatile length as they reach a little longer (225mm on Nikon and 240mm on Canon). Featuring a raft of specification acronyms, it promises high performance in a well-priced package, but does the reality live up to the billing?

The zoom range 70-200, or thereabout, is one of the real classic lenses, an absolute “must” for sports and photojournalism. The faster the maximum aperture the better, but most important of all it must be a good performer. Tamron’s SP 70-200mm f2.8 Di VC USD has the right specifications and a price tag that is very attractive, especially when you see how good it is.
